If the printed image is light due to the life of the toner, you can temporarily improve the print quality by redistributing the toner(Shake the toner cartridge), however, you should replace the toner cartridge to solve the problem thoroughly.
4.5.3 Redistributing Toner
When toner is low, faded or light areas may appear on a printed page. You may be able to temporarily improve the print quality by redistributing the toner. The following procedures may allow you to finish the current print job before replacing the toner cartridge. 1) Grasp the front cover and pull it toward you to open. 2) Remove the toner cartridge from the printer 3) Gently shake the toner cartridge from side to side five or six times to redistribute the toner.
Note :
If the toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.
Note :
Avoid reaching too far into the printer. The fusing area may be hot. To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.
4) Reinsert the toner cartridge into the printer. Ensure that the toner cartridge snaps into place. 5) Close the front cover. Make sure that the cover is securely closed.

4.6 Bad Environment of The Software
4.6.1 The printer is not working (1)
· Description While Power turned on, the printer is not working in the printing mode.
Check and Cause 1. Run Self-Test Mode : Turn the power on while pressing the test printing button for 2 or 3 seconds before printing works.
Solution 1.Check the power of the printer and perform the SelfTest. If the test printing works, that means no problems in the printer itself. If the test printing does not work, that means bad functioning of the printer(not because of software). Perform DCU to check the Error Status. 2. Replace the printer cable. If the problems not solved even after the cable replaced, check the amount of the remaining tone. (refer to Toner Cartridge Service 7.4) 3. Check if the connection between PC and printer port is proper. If you use windows, check if the printer driver in the controller is set up. If the printer driver is properly set up, check in which program the printing is not working. The best way to find out is to open the memo pad to check the function of printing. If it is not working in a certain program, adjust the setup the program requires. Sometimes, the printout is normal within the Windows basic programs, but it's not working in a particular program. In such case, install the new driver again. If not working in the Windows basic program, Check the setup of the port of CMOS is on ECP. And check the address of IRQ 7 and 378
2. Check if the PC and the printer is properly connected and the toner cartridge installed.
3. Printing is nor working in the Windows.
4. Check if the printer cable is directly connected to peripheral devices
4. If the scanner needs to be connected to the printer, first the remove the scanner from the PC to see if the printer is properly working alone.

4.6.2 The printer is not working (2)
· Description After receiving the printing order, no response at all or the low speed of printing occurs due to wrong setup of the environment rather than malfunction of the printer itself. Check and Cause 1. Secure more space of the hard disk. Solution 1. Not working with the message 'insufficient printer memory' means hard disk space problem rather than the RAM problem. In this case, provide more space for the hard disk. Secure more space using the disk utilities program. 2. The connection of the cable and printer port is not proper. Check if the connection is properly done and if the parallel port in CMOS is rightly set up.
2. Printing error occurs even if there is enough space in the hard disk.
3. Check the parallel-port-related items in the CMOS Setup.
3. As a printer port, Select ECP or SPP among SPP(Normal), ECP, and EPP modes(increase printing speed) SPP normal mode support 8-bit data transfer, while ECP Mode transfer the 12-bit data.
4. Reboot the system to print.
4. If the regular font is not printing, the cable or the printer driver may be defective. Turn the PC and printer off, and reboot the system to print again. If not solved, double-click the printer in my computer If the regular fonts are not printed this time again. the cable must be defective so replace the cable with new one.

4.6.3 Abnormal Printing
The printing is not working properly even when the cable has no problem. (even after the cable is replaced) If the printer won't work at all or the strange fonts are repeated, the printer driver may be defective or wrong setup in the CMOS Setup. Check and Cause 1. Set up the parallel port in the CMOS SETUP. Solution 1. Select SPP(Normal) or ECP LPT Port the among ECP, EPP or SPP in the CMOS Setup.
· Description
2. Printer Driver Error.
2. Check the printer in My Computer.(to see if the printer driver is compatible to the present driver or delete the old driver, if defective and reinstall the new driver)
3. Error message from insufficient memory. (The printing job sometimes stops or due to insufficient virtual memory, but it actually comes from the insufficient space of the hard disk.)
3. Delete the unnecessary files to secure enough space of the hard disk and start printing job again.

4.6.4 SPOOL Error
To spool which stands for "simultaneous peripheral operations online" a computer document or task list (or "job") is to read it in and store it, usually on a hard disk or larger storage medium so that it can be printed or otherwise processed at a more convenient time (for example, when a printer is finished printing its current document). Check and Cause 1. Insufficient space of the hard disk in the directory assigned for the basic spool. Solution 1. Delete the unnecessary files to provide more space to start printing job.
· Description
2. If the previous printing error not solved.
2. If there are some files with the extension name of ****.jnl, Delete them and Reboot the Windows to restart printing job.
3. When expected to collide with other program.
3. Shut down all other programs except the current one, if possible.
4. When an application program or the printer driver is damaged.
4. Delete the printer driver completely and reinstall it.
5. When some files related to OS are damaged or virus infected.
5 After rebooting the computer, check for viruses, restore the damaged files and reinstall the program to do the printing job.
6. Memory is less than suggested one.
6. Add up enough memory to the PC.
How to delete the data in the spool manager. In the spool manager, the installed drivers and the list of the documents waiting to be printed are shown. Select the document to be deleted and check the delete menu. If you intend to delete the current document being printed, the data being transferred to the printer will be put out and then the document is removed. Before choosing the document, the menu is still inactive. Or put the document out of the list and repeat the routine as in the above or finish the spool manager.
